I posted this some time ago and never heard any further research on the subject. Seems pretty important to me.....
Silver can be toxic to nerve cells in the brain and spinal cord, but is normally prevented from entering those areas by the blood-brain barrier. If you mix silver with DMSO then the DMSO will carry the silver with it easily through the blood barrier. The following website had this to say about CS and Brain cells. http://colloidalsilver.hypermart.net/silver/contactus.html http://www.quantumbalancing.com/csfq.htm What is colloidal silver? Are there any dangers or side effects? The Environmental Protection Agency's Poison Control Center reports no toxicity listing for Colloidal Silver. Regular ingestion of colloidal silver can act as a second immune system by assisting the body in the war against invading micro-organisms. Unlike pharmaceutical antibiotic which destroy beneficial enzymes, colloidal silver leaves these tissue-cell enzymes intact. Colloidal Silver, if used sensibly, is completely non-toxic and will not harm the immune system in any way. Critics of colloidal silver will often warn that regular consumption of colloidal silver might lead to Argyria, a bluish/ grey discoloration of the skin. Dr. Bob Beck debunks this statement as a scare tactic by pro-pharmaceutical interests. Dr Beck has indicated that Argyria is caused by silver compounds, such as silver nitrate, silver sulfate, silver sulfadiazine, etc., and not micro-particles of pure elemental silver. Apparently, silver colloids are mostly absorbed in the upper gastrointestinal tract, since colloidal silver does not seem to adversely affect friendly bacteria in the lower intestines. Silver can be toxic to nerve cells in the brain and spinal cord, but is normally prevented from entering those areas by the blood-brain barrier. Silver has not demonstrated any evidence of carcinogenic activity. The body eliminates excess silver via the metallothiones. These ubiquitous proteins, first characterized in 1957, have the property of binding with heavy metals, such as silver, into metal-thiolate-cluster structures which aid in transportation, storage, and elimination of nonessential trace metals which enter the body. -- The silver-list is a moderated forum for discussion of colloidal silver.
